Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456414, here are decompositions:

53 + 31456361 = 31456414
83 + 31456331 = 31456414
137 + 31456277 = 31456414
167 + 31456247 = 31456414
173 + 31456241 = 31456414
251 + 31456163 = 31456414
293 + 31456121 = 31456414
347 + 31456067 = 31456414

Showing the first eight; more decompositions exist.
